GROWLINK HARDWARE · NUTRIENT DELIVERY

Exact Nutrients. Maximum Yields.

Growlink’s nutrient delivery systems eliminate mixing guesswork and deliver precise pH and EC levels directly to your canopy — controlled through Growlink OS and synchronized with your crop Blueprints.

WHY IT MATTERS

Fertigation is where yield  
is won or lost.

Inconsistent nutrient delivery is one of the most common and most costly sources of yield variability in commercial cultivation. Wrong pH. Missed EC targets. Manual mixing errors. Recipe drift between shifts. Each one compounds across rooms and runs — reducing quality, increasing waste, and making results harder to predict.
‍
Growlink’s nutrient delivery systems eliminate these variables. Every feed event is defined in your Blueprint, executed automatically, and logged in Growlink OS — so your canopy gets exactly what it needs, every time, with proof.

CONFIGURATIONS

One system.  
Every fertigation strategy.

Growlink supports direct inject, single batch, and multi-batch configurations — controlled through the same Growlink OS interface regardless of how your facility delivers nutrients.

Configuration is defined in software. Hardware executes it. One platform regardless of which approach your operation uses.

Direct Inject

Nutrients injected directly into irrigation lines in real time. Fastest response to crop conditions. Minimal tank infrastructure. Ideal for operations that need immediate adjustment capability and frequent recipe changes.

Single Batch

A single batch tank mixed and delivered to one or more zones. Clean and straightforward. Ideal for operations running standardized recipes across consistent room conditions.

Multi-Batch

Multiple batch tanks running different recipes simultaneously. Cultivar-specific feeds across multiple rooms or zones without cross-contamination. Ideal for multi-strain commercial operations and facilities running different growth stages simultaneously.

NDS AND NDK

Two ways to deploy. 
One platform.

Whether you need a fully assembled turnkey system or a self-install kit, both options run the same Growlink OS nutrient delivery software.

NDS — Nutrient Delivery System

Turnkey professional deployment.

Fully assembled and professionally installed. The NDS is engineered for large commercial facilities where deployment quality, uptime, and performance are non-negotiable. Built with powder-coated steel, HE Anderson injectors and pumpers, and GF Signet sensors. UL-508A listed controls. Rugged 1" to 2" Schedule 80 PVC pipes handle high flow rates up to 80 GPM. Optional 19" responsive touch panel for full local access at the system.

Best for: Multi-site commercial operations, new facility builds, and operators who want a validated, professionally commissioned system.

NDK — Nutrient Delivery Kit

Self-install with full platform access.

All components included. Self-installed. The NDK brings Growlink’s nutrient delivery software and automation to operations that prefer to manage their own installation. Same Growlink OS platform. Same Blueprint integration. Same reporting and agent oversight.

Best for: Operations with in-house engineering capability, expansion rooms, and facilities adding nutrient delivery to an existing Growlink deployment.

BUILT FOR COMMERCIAL OPERATIONS

Hardware engineered to perform.

Growlink nutrient delivery systems are built with commercial-grade components designed for the demands of large-scale, continuous cultivation operations.

Scale without bottlenecks

Rugged 1" to 2" Schedule 80 PVC pipes handle high flow rates up to 80 GPM — so your nutrient delivery system never becomes the bottleneck in a high-density commercial facility.

Bulletproof crop protection

Redundant pH, EC, and temperature sensors trigger automatic emergency shutdowns before bad water reaches your plants. HE Anderson injectors and GF Signet sensors deliver industry-leading measurement accuracy.

Commercial compliance

UL-508A listed controls meet the highest commercial electrical safety standards. Built for facilities where compliance is not optional and where hardware reliability is a business requirement.

GROWLINK OS INTEGRATION

Hardware that  
follows the recipe.

Nutrient delivery in Growlink is not a standalone system. It is fully synchronized with your Blueprints, your automation rules, and your AI agents — so every feed event is part of a larger cultivation strategy.

Blueprint-synchronized feeding

Every nutrient recipe is defined inside your crop Blueprint — EC targets, pH ranges, feed timing, and transitions between crop stages. Nutrient delivery executes automatically from the Blueprint. No manual scheduling. No recipe drift between shifts.

Automated recipe scheduling

Seamlessly switch nutrient formulas based on crop phase without manual oversight. The system transitions between vegetative, flowering, and finishing formulas on schedule — with every change logged and traceable.

Live dashboard and event queue

Real-time overview of feed events, flow totalizers, stock tank levels, and water transfers inside Growlink OS. Your team sees exactly what is happening with nutrient delivery without being physically present at the system.

Stock tank tracking

Precise reporting on stock tank levels and consumption rates. Know when to reorder before you run out. Track input costs per room and per run with data that feeds directly into your operational reporting.

AGENTIC CULTIVATION™

Agents that optimize every feed.

The Irrigation Agent and Insights Agent monitor nutrient delivery performance continuously — flagging EC drift, identifying runoff inefficiencies, and recommending adjustments that improve consistency run over run.

Detect EC or pH deviation from Blueprint targets and surface corrective recommendations before crop stress occurs.

Identify patterns in runoff data that indicate over- or under-feeding across rooms or zones.

Recommend feed timing and formulation changes based on substrate response and historical Blueprint performance.

Agents recommend. Your team decides. Every recommendation and every decision is logged in Growlink OS.

INSTALLATION AND COMMISSIONING

Installed right.  
Performing from day one.

NDS deployments are supported by Growlink’s installation and commissioning team. Professional installation, system validation, and go-live sign-off — so your nutrient delivery system performs correctly from the first feed event.

Installation and commissioning

Professional deployment with full system validation before go-live.

Extended warranty

Hardware protection for operations that cannot afford unplanned downtime or replacement costs.

Cultivation advisors

Post-deployment optimization support to dial in recipes, improve consistency, and reduce waste.

What operators achieve with
Growlink nutrient delivery.

“We went from shooting for 60,000 grams of fresh frozen a table to averaging 80–90,000 grams, and even breaking 100,000. We even used less water and fewer nutrients, because Growlink lets us dial everything in.”
